WARP BEAM.

The hub 7 is of '7J 13 i ment between the beam head A and the barrel comprises a disk 9 having a peripheral fiange 10 wh-ich fits within a counter-bore 11 in the end of the barrel. cured to the inner face of the main disk 1 by means of spot welds 12. It will be seen that the flange 10 serves to support the barrel B in concentric relation to the shaft O rllhe flange 10 is formed to provide a series of clutch jaws adapted to engage similar jaws formed upon the peripheral flange 13 of a disk 14. The flange 13 fits within the counterbore 11. The disk 14 is secured by means of lag screws 15 to a wooden head 16 on the central shaft C, said head being secured to the barrel B by means of screws 17.

rlhe beam head A` is clamped tightly against the end of the barrel B by a nut 18 turned on a screw-threaded portion of the shaft C. To lock the nut against rotation, a washer 19 is interposed between the nut and the head, said washer having lugs 20, certain of which are bent to lie in openings in the bracing disk 3, the remaining lugs being bent into engagement with the perimeter of the nut.

lt will be apparent that 'the'beam head construction herein disclosed is relatively light, provides the necessary strength to resist centrifugal force, and is also sutiiciently rigid to prevent spreading due to the pressure of the yarn load. By reason of the use of sheet metal and the system of bracing herein described, the beam head is not apt to be damaged by rough handling.

The disk 5, the spacing sleeve 8 and that portion of the disk 1 which lies within the circle defined by the barrel may be viewed as a truss consisting of the compression member 5, the chord or tension member 1 and the strut 8. It will be seenthat this truss imparts great rigidity to that portion of the beam head which is clamped between thenut 18 and the barrel B and prevents any bending of the beam head in that region. Likewise, the disks 1 and 3 and the sleeve 8 constitute a truss which effectively resists forces tending to spread the beam heads apart. While the form of truss herein disclosed serves its intended purposes very well, other forms of trusses and other means of spacing the disks 1 and 3 apart and of securing said disks together may be employed without departing from the scope of the invention hereinafter claimed.

The clutch ianges 10 and 13 being rela` tively remote from the axis, are advantageously located to resist that tendency to relative rotation between the barrel and the head which occurs upon sudden stoppage of the rapidly rotating beam.

The construction shown is well calculated to prevent bending of the shaft C. There is consequently no liability of movement be- The disk 9 is seinternist tween the head and the barrel which might result in the opening of a crevice between said parts.
